Learn How to Solder With This Circuit Board Christmas Tree Kit

Do you know how to solder? I do, but only because I try to repair all my electronics after they break, then end up having to buy new ones anyways after I break them even more. But for those of you who still need some practice (myself included, apparently), there’s this 3D Christmas Tree Soldering Kit (affiliate link). It’s a circuit board Christmas tree you have to assemble and solder yourself, gaining some much-needed experience in the process. And, if you’re like me, set off the smoke alarm at least a half dozen times.

Available in 3- and 7-color models, the STEM kits include everything you need to construct your own 36-light tree, EXCEPT a soldering iron. You have to provide that on your own. And if you don’t have one, DO NOT try to use a lighter and the foil from gum wrappers; you’re not McGyver. Or at least I’m not.

I love fun little DIY projects like this. I feel so accomplished when I complete one, even if they were designed with kids in mind. I might not be a kid in mind, but I am a child at heart. And, okay, my wife says I do have the mind of a 4th grader sometimes. Most of the time, actually.

MesoGlue Room Temperature Metallic Glue: Universal Solder

Welding and soldering form strong bonds that conduct electricity and heat, but they require high temperatures that can be dangerous to both people and equipment. A new company called MesoGlue claims that its eponymous metallic glue has all the advantages of welding and soldering but with the ease of use of polymer adhesives.

MesoGlue is made of metallic nanorods that are spaced just right such that a pair of coatings can lock into each other. It has two types: one made of silver and another made of copper “with other metals.” The latter can fuse objects together with very little pressure, like ordinary glues. The silver MesoGlue on the other hand needs a higher pressure to fuse without gaps, but the resulting bond has a higher electrical and thermal conductivity than the copper alloy MesoGlue.

I know that the concept of nanomaterials is hard to grasp, but that intro video is oversimplified and didn’t show the product itself. It doesn’t help that the company has no other demo videos as of this writing. That said, MesoGlue says it’s willing to demonstrate its wonder glue and join nearly any flat surface, but only at their facility.

Boldport Buggy DIY Toy: LEDybug

Work on your soldering skills with Boldport’s cute soldering kit. The Buggy has a beautiful ladybug-shaped circuit board, six candle-flicker LEDs and adjustable antennae and legs. Its legs hold the resistors, so the cute tubing socks are not just for show but for insulation as well.

Boldport founder Dr. Saar Drimer originally designed Buggy as a badge for this year’s Hardwear.io conference. He then revised it into this soldering kit.
